FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a
smaller fuel tank opening. The special nozzle on pumps
with unleaded fuel will fit it, but the larger nozzle on
pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the
specifications of ASTM D4814 in the U.S.A. and CGSB
3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the three±way catalyticconverter to lose its effectiveness and theemission control system to function improperly.Also, this can increase maintenance costs.
Octane rating
Select premium unleaded gasoline with an Octane
Rating of 91 (R esearch Octane Number 96) or higher
for optimum engine performance. However, if such
premium type cannot be obtained, you may
temporarily use unleaded gasoline with an Octane
Rating as low as 87 (Research Octane Number 91). Use of unleaded fuel with an octane number or rating
lower than stated above will cause persistent heavy
knocking. If severe, this will lead to engine damage.
If your engine knocks ...
If you detect heavy knocking even when using the
recommended
fuel, or if you hear steady knocking while
holding a steady speed on level roads, consult your
Lexus dealer.
However, now and then, you may notice light knocking
for a short time while accelerating or driving up hills. This
is no cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain
detergent additives to avoid build±up of engine
deposits.
For further details, ask your Lexus dealer or a local
gasoline retailer.
